The fact that its not Biblical with respect to this dictionary does not necessitate that it can't or shouldn't be made available for the MySword community. The fact that there are English speaking speaking people, such as missionaries and etc in Japan, your dictionary might just prove to be a valuable resource to them, providing they are MySword users. Moreover, as to how many Japanese MySword users there are, this resource might also be just the the thing they are looking for.

So, bearing all of that in mind, I recommend that you upload it, and from time to time check to see how many have downloaded it.
